Extraversion/Introversion --> Front/Back: I don't particularly like this one. It may be true from a brain function perspective (which is an interesting field I'd like to look into more), but it doesn't help people understand what the dichotomy is about. When I explain it to people, I usually describe it as "outwardly-focused" and "inwardly-focused", which is oversimplifying a bit, but better than nothing.

Sensing/Intuition --> Empirical/Conceptual: I like "Conceptual" for "Intuition", and I often describe it like that to people ("big picture, concepts and ideas"). "Empirical" I'm less sure of. It's more of a Te word. But I understand where he's going with it. I usually describe this dichotomy to people as "details in the here-and-now" vs. "general concepts and impressions in the big picture".

Thinking/Feeling --> Inanimate/Animate: These may be true in a general sense (Logical types generally focus on inanimate subject matter, Ethicals on animate), but since socionics itself is an example of Logical examination of animate subject matter, I think it actually obscures the meaning of the dichotomy rather than clarifies it.

Judging/Perceiving --> Left brain/Right brain: I actually really like this. Certainly more people are familiar with the concept of Left brain/Right brain than are familiar with the specialized socionics definition of "Judging" and "Perceiving". I'm just a little cautious about whether the idea of Left brain/Right brain matches up 100% with Judging/Perceiving -- if it does, then I'm all for this way of describing the dichotomy.
